CARPET-STRETCH ER.

SPECIFICATION forming part of Letters Patent No. 412,842, dated October 15, 1889.

Serial No. 274,065. (No model.)

To all whom it may concern:

Be it known that I, CHARLES F. COOPER, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Carpet-Stretchers, of which the following is a specification.

The object of my invention is to improve the construction of carpet-stretchers so as to render them more efficient in operation, cheaper to manufacture, and more convenient in transportation than formerly.

The invention consists in the construction, combination, an d arrangement of parts to this end, as hereinafter fully set forth and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of the invention; Fig. 2, a longitudinal section of the same, and Fig. 3 a similar view of a modified form of head.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A is the head, provided with a series of teeth 6 e, adapted to catch into the carpet in the usual way. The central portion of the head, on its forward side, extends forwardly and turns up to form a stirrup A. I11 themiddle of the head is a lug d, to which is pivoted the handle C. The serrated hook-bar B passes under the stirrup A, through a hole f in the head, and over the top of the lug (l, the top of which is shaped to correspond with the notches in the bar. To the handle C, above the bar B, is pivoted a pawl D, the forward end of which extends down under the bar in the form of a stirrup, the transverse portion 1) engaging with the notches therein. A spring a holds the pawl in engagement with the said notches. The pawl may be provided with a short projection c to serve as a finger-piece in disengaging the same.

The operation of the device will now be readily understood. The spur B is driven into the floor near the wall and the teeth e e are pressed into the carpet. Then by a reciprocating motion of the handle C the head is advanced toward the spur, the lug d holding while the pawl advances, and vice versa. It will be seen that as the carpet is drawn the natural tendency will be to force the bar B down upon the lug d, and that the position of the parts is such as to keep the head level and prevent any undue turning or twisting of the same in any direction.

The device consists of but few parts, as will be seen, and these may be chiefly made of malleable iron or the like, thus rendering it cheap to manufacture.

The lug d may be a component part of the head, or a separate piece pivotally attached thereto, in which latter case the handle may be turned lengthwise of the head for convenience in shipping, the various parts of the de vice then occupying but little space.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, isr In a carpet-stretcher, the combination of the head A, having stirrup A, forming a bear- 7o ing for the smooth upper face of the hookbar, and lug cl and teeth 6 e, the hook-bar B, having notches on the under side, the handle C, pivotally connected with the head, and the pawl D, pivoted to the handle above said bar, having the catch 1), substantially as and for the purpose set forth.

In testimony whereof I affix mysignature in presence of two witnesses.

CHARLES F. COOPER. Witnesses:
